Purpose: This work aimed at evaluating the properties of the ethyl silicate-based coating
that can be applied on low carbon steel.
Design/methodology/approach: Two mixture ratio types (2:1, and 3:2) of resin and
hardener respectively were used to prepared two specimen models (A and B).
Findings: It found that some mechanical properties (tensile, hardness, and impact strength)
of ethyl silicate resin were evaluated according to standard criteria.
Research limitations/implications: The effect of heat treatments at various temperatures
(100, 150, and 200°C) and holding at different times (10, 20 & 30) min on hardness was
investigated.
Practical implications: Moreover, an open circuit potential corrosion test with a solution
of 3.5% Sodium Chloride at room temperature and 60°C was used to determine the
corrosion resistance of low carbon steel specimens coated with the two mixture types.
Originality/value: The effects of mixture ratios (for resin and hardener) and heat treatment
conditions on properties of ethyl silicate-based coating were studied. From obtained results,
acceptable values of tensile, hardness, and toughness were recorded. Increasing heat
treatment temperature and holding time leads to enhance hardness for both model types. An
open circuit potential (OCP) tests show that there is an enhancement of protective properties
of ethyl silicate coatings with mixture type B in comparison with type A was achieved.
Generally, the results indicate that specimen model B has higher properties as compared
with specimen model A.
